Each 14-day period was separated by a 7-day washout. With compression, participants wore graduated compression tights during sleep after daytime acclimation. Co-primary outcomes were between-condition differences in overnight circumference change at the ankle, calf, and thigh. Secondary outcomes were subjective sleep quality and morning fatigue. Self-reported morning leg swelling was assessed at each time point. Mixed-effects models were used, with Holm adjustment for three primary outcomes.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Forty-six participants were randomized and 44 completed both periods. Compared with no compression, compression resulted in greater overnight reductions at the ankle (least squares mean difference, \u22120.23\u00a0cm; 95% confidence interval, \u22120.33 to \u22120.13; adjusted\n                      <jats:italic toggle=\"yes\">p<\/jats:italic>\n                      = 0.0001), calf (\u22120.35\u00a0cm; \u22120.52 to \u22120.18; adjusted\n                      <jats:italic toggle=\"yes\">p<\/jats:italic>\n                      = 0.0004), and thigh (\u22120.28\u00a0cm; \u22120.47 to \u22120.08; adjusted\n                      <jats:italic toggle=\"yes\">p<\/jats:italic>\n                      = 0.0066).

Although the differences were modest (approximately 2\u20134\u00a0mm) and their clinical importance remains uncertain, the accompanying reduction in perceived morning swelling suggests that these changes may have perceptible relevance to participants. Nighttime compression may facilitate the overnight reduction of transient lower-limb swelling under everyday living conditions.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/02683555261497310","type":"journal-article","created":{"date-parts":[[2026,10,11]],"date-time":"2026-10-11T14:54:33Z","timestamp":1791730473000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Effects of nighttime graduated compression tights on overnight changes in lower-limb circumference in healthy young women with subjective leg swelling: A randomized crossover trial"],"prefix":"10.1177","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9738-0438","authenticated-orcid":false,"given":"Nobuyuki","family":"Wakui","sequence":"first","affiliation":[{"name":"Hoshi University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Asuka","family":"Ozaki","sequence":"additional","affiliation":[{"name":"Hoshi University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuna","family":"Koakutsu","sequence":"additional","affiliation":[{"name":"Hoshi University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hazuki","family":"Ogami","sequence":"additional","affiliation":[{"name":"Hoshi University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuna","family":"Hirota","sequence":"additional","affiliation":[{"name":"Hoshi University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Manaka","family":"Kawakami","sequence":"additional","affiliation":[{"name":"Hoshi University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ayaka","family":"Aida","sequence":"additional","affiliation":[{"name":"Reckitt Benckiser Japan Ltd."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shunsuke","family":"Shirozu","sequence":"additional","affiliation":[{"name":"Hoshi University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yoshiaki","family":"Machida","sequence":"additional","affiliation":[{"name":"Hoshi University"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2026,10,11]]},"reference":[{"key":"e_1_3_8_2_2","first-page":"102","article-title":"Edema: diagnosis and management","volume":"88","author":"Trayes KP","year":"2013","unstructured":"Trayes KP, Studdiford JS, Pickle S, et al.
